I'm getting this error message:
Could not create element volume, check your installation
(I think this is the correct translation, but I'm not sure :-P)
did you recently change over to udev and not adjust your sound settings for user?
I am not your friend
Take a look in the above thread, it's just about your problem.

Ah, indeed, it's fixed now. The problem was I couldn't select ALSA from the gstreamer-properties. So I did what was asked, upgraded gstreamer (but it was already up-to-date, so basicly, reinstall) and ALSA was available. It works now!
i had the same problem with gnome last week, and a simple "gst-register" on the console solved this problem.
if this can help other users...
